Conservation and Dissipation of Energy Crossword Puzzle

QUESTIONS LIST:

• nuclear energy : a term used to describe energy when it is stored inside atoms. it is another name for nuclear energy.
• chemical energy : a term used to describe energy when it is stored in chemical substances. food, fuel, and batteries all store chemical energy.
• efficiency : the proportion of input energy that is transferred to a useful form. a more efficient machine wastes less energy.
• joules : a unit for measuring energy.
• system : a set of things being studied. for example, a kettle, the water in it, and its surroundings form a simple system.
• dissipated : spread out.
• epe : short version of a name used to describe energy when it is stored in stretched or squashed things that can stretch back to their original shape. another name for ‘strain energy’.
• energy : something that is needed to make things happen or change.
• kinetic energy : a term used to describe energy when it is stored in moving things.
• power : the amount (rate) of energy transferred per second. the units are watts (w).
• thermal energy : a term used to describe energy when it is stored in hot objects. the hotter something is, the more thermal energy it has. sometimes called ‘heat energy’.
• useful energy : energy transferred to where it is wanted in the way that is wanted.
• wasted energy : energy that is not usefully transferred.
• watts : the unit for measuring power. 1 watt = 1 joule of energy transferred every second.
• work : the energy transferred by a force. work done (joules, j) = force (newtons, n) x distance moved in the direction of the force (metres, m).
